Abstract

A virtual network device includes a framing circuit that determines a virtual exit device associated with each input frame of a plurality of input frames based on a frame type for each input frame. A plurality of first encapsulated frames is formed based on encapsulation of the plurality of input frames. A plurality of transmit virtual ports, coupled to the framing circuit, determines next hops in a virtual network for the plurality of first encapsulated frames based on the virtual exit devices corresponding to the plurality of first encapsulated frames, and encapsulates the plurality of first encapsulated frames to form a plurality of second encapsulated frames. A transmit virtual switch selectively couples one or more transmit virtual ports to a network physical port based on whether a full signal from the one or more transmit virtual ports has been received by the transmit virtual switch.
